  • Flame retardant porous plastic resins
    Patent number: 11154737
    Abstract: Described are flame retardant, porous plastic flame arrestors. The flame retardant, porous plastic flame arrestor is formed by irradiating a flame retardant polymer resin to achieve a fractional melt index, grinding the flame retardant polymer resin into a powder, and sintering the flame retardant polymer resin to form a porous structure. Irradiating the flame retardant polymer resin increases the resin's molecular weight and reduces the resin's melt index through crosslinking.
    Type: Grant
    Filed: December 7, 2015
    Date of Patent: October 26, 2021
    Assignee: M.A. INDUSTRIES, INC.
